About this study
Official title: Therapeutic Effect of Peripheral Magnetic Stimulation Generated by the Super-inductive System to Treat Patient With Post-stroke Shoulder-hand Syndrome
Shoulder-hand syndrome is a common complication following stroke, constituting of excessive pain, swelling, heat, limited range of motion, and trophic change of the affected limbs. It not only has an extensive negative impact on both physical and psychological aspects of a stroke patient's well-being, but also impose burden on the health care system and the patient's family. Despite its relatively high incidence, there is neither well-established treatment protocol, nor high quality evidence for a single effective treatment. The objective of the present study is to investigate the efficacy, including pain, spasticity, and subluxation reduction, muscle strengthening, and shoulder range of motion improvement, of high-intensity peripheral magnetic stimulation generated by the super-inductive system to treat patients with post-stroke shoulder-hand syndrome.
Read the detailed description
The present study aims to investigate the therapeutic effects achieved by the peripheral magnetic stimulation for treating post-stroke shoulder-hand syndrome. The investigators plan to use high-intensity peripheral magnetic stimulation generated by the super-inductive system for treatment of post-stroke shoulder-hand syndrome. In terms of study design, the treatment group will receive 10 sessions of high-intensity peripheral magnetic stimulation 5 days a week for 2 weeks, with physical and occupational therapy kept as usual; while the control group will only receive conventional physical and occupational therapy. Comprehensive assessment, including history taking and physical examination testing for muscle strength, spasticity, shoulder range of motion, before and after the intervention will be conducted for evaluation.

What is being measured
The primary outcome is the main question the study is designed to answer.

Secondary outcomes (3)
strength of upper limb
change of score of Manual muscle testing (0-5, higher scores mean a better outcome)
Measured: 0,7, 14,28 days
spasticity of upper limb
change of Modified Ashworth Scale (0-4, higher scores mean a worse outcome)
Measured: 0,7, 14,28 days
range of motion of shoulder
Change in range of motion in degree in flexion, abduction, external and internal rotation (0-180 degrees,higher scores mean a better outcome)
Measured: 0,7, 14,28 days

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pain (time frame: 0,7, 14,28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
